' of lVashburn and State of VVisc'onsin, have kinvented new and usefulImprovementseinl heel-Flangeilers, of which the following is aspecification.

The object ofthe invention is to provide an efficient means forsupplying oil to-'the wheel flanges of cars and like vehicles under suchconditions asfto beoperative only when required or when the wheels arein motion, or in other words as applied to railway and similar cars whenthe engine is in operation or when steam hasbe'enused, particularly asdevices of this class are generally employed in connection with theangeslof the locomotive wheels, and with this object. in view theinvention consists in a construction and combination of part-s of whicha preferred embodiment is shown in the accompanying drawing, wherein: y

Figure l is a plan View of the apparatus with the oil dispensing nozzlesdisposed in operative relation with car wheel fianges.

Fig. 2 is an elevational view of the same. .Fig 3 is a detail sectionalview of one of the nozzles.

The purpose of the apparatus is to provide for feeding oil, grease orsimilar su1table lubricant to the wheels under' steam pressure only whenthe steam is turned on for operating the engine of the locomotive, andto this end the feed pipe 10 thereof should be connected by a steampressure pipe 1l, which may have any suitable controlling valve or stopcock 12 with a convenient steam supply pipe 13 into which steam will beturned by opening the throttle of the 'engine and which of course can beeffected in a variety of ways without modifying the operation of thisapparatus and hence without necessitating specific illustration in thisconnection. The feed pipe is arranged terminally in communication withnozzles 1li which are respectively disposed in operative relation withcar wheels indicated at 15, a

single apparatus ordinarily being employed arranged in angular positionsboth withrelation'to ahorizontal and with relation to vertical planesembracing the feed pipe 10. In

other words'the nozzles jincline either for# wardly or rearwardlysubstantially at an angle of 45 degrees to a horizontal plane, andyinwardlyor toward each other at an angle approximating 45 degrees sothat the outlet ends of the reduced" nozzle tips 18 impmge against thewheels at the line represented by. the angle between the tread fand'flange .surfaces of the same and in angularrelation with bothsurfaces. T his nozzle tip is mounted for axial movement in the sleeve19 which is connected as by a threaded joint with the casing 21 ofthenozzle, the passage through the tip being reduced to a very smalldiameter and the inner end of the tip being provided with a followerhead 22 fitted to the bore of the sleeve shown at 23 where it is exposedto pressure in the casing of the nozzle. This tip is free to moverelative to the casing and is held extended ywith its outlet extremityin contact with the the extremity of the feed pipe10 by a collar 24 isarranged a. piston valve 25 in connection with which is arranged aspring 26 adapted toyieldingly hold the valve in position to close aby-pass 27 leading from a steam chamber 28 in direct communication withthe feed pipe 10 and the oil chamber represented the source and issupplied to the feed pipeV 10 it acts upon the piston valve to exposethe by-pass and thus permit fluid pressure to be applied to thelubricant to discharge the same through the tip of the nozzle. Theby-pass is also preferably provided with a needle valve 29 adapted forengagement with a suitable seat 30 and designed to serve as a means ofpermanently cutting off'the sup-` ply of lubricant or of regulating thepressure conveyed by the by-pass and hence that which is applied as ameans of expelling the lubricant. It will be noted that in addition tothe reduction. or throttlng action incident to the use of the by-passand the needle valve there is a reduction as between the oil orlubricant containing chamber of `the nozzle and the discharge tip.

What is claimed is: Y i

vl. A Wheel flange oiler having a nozzle provided with an extensibledischarge tip having a follower head, a casing with which the dischargetip is removably connected, the said casing being provided with alongitudinal bore, a spring actuated piston valve housed in said bore,the casing being formed with a by-pass communicating with the bore atopposite ends of the piston valve and adapted to be closed at one end bysaid valve, and means for communicating fluid pressure to the casing toactuate the valve to open said by-pass as herein shown and specified. 2.A wheel flange oiler having a nozzle provided with an extensibledischarge tip having a' follower head, a casing with which the dischargetip is removably connected7 the said casing being provided with alongitudinal bore, a spring actuated piston valve housed in said bore,the casing being formed With a by-pass communicatngwith the bore atopposite ends of the piston valve and adapted to be closed at one end bysaid valve, a needle valve carried by said casing and controlling thesaid by-pass, and means for communicating fluid pressure to thercasingto actuate the valve to open said by-pass as herein shown, andspecilied.

In testimony whereof I alix my signature.
